Horowitz admits to understanding the Frozen is "important to millions of fans of Frozen, and we want to do our best to honor what they loved about that movie." He also notes the most crucial element in arc creativity is to not mess up any potential story lines for a possible Frozen movie sequel, while fitting into Once Upon A Time's world.

"We want it to walk that line of being part of the Once Upon a Time universe, but also feel like part of the Frozen world."

And it seems like Disney's made some points crystal: no villainous edits. In previous character arcs, good guys suddenly go back. Peter Pan is a great example of possible branding issues. He's the snotty little boy who won't grow up, but isn't truly bad.

Kitsis points out that they've already incorporated some of the Frozen themes.

Like Hook’s emerging arc of some humanity, a villain is not always a villain. "And the idea of a villain who is not actually a villain—one of the things we loved about Elsa is she went away not because she was a villain, but because she didn’t want to hurt anyone and felt different." He specifically references Rumpelstiltskin for this since the golden man also wears the Beast's crown.

And that doesn't even count the 'true love's kiss,' which is a heartbeat for the entire show. Unless you're Sheriff Graham, who's now doing time as Christian in 50 Shades of Grey.

True love doesn't mean romantic love, either.

Horowitz even points out that the key pieces to Once Upon A Time have always been about "an act of true love as opposed to the traditional romantic love." Look at Regina and Emma teaming up to help their son, Henry. It doesn't matter if they get along or agree on how to raise him--only that they put aside selfish desires to make sure he's secure and happy.

While the themes are the same in both Disney properties, they haven't copied each other. And let's face it: true love of any kind is the basis for most fairy tales and myths.

Plus, the arc is a limited-run where there's a little play time break between Frozen and Once Upon A Time's world "but it’s a close-ended story." So unlike the Neverland peek, there won't be a villain looking for revenge and love.

As mentioned earlier, OUAT love is about family, connection, a solid foundation in the middle of chaos. "What we love about Elsa is that she is uncomfortable with her power, she’s lonely," and that's been explored with Regina a lot over the seasons.

Maybe the overly powered beings will team and learn a little bit about taking away loneliness when you've got someone that understands…and isn't your evil mother, in the case of Regina. Plus, the whole theme of the first half will be more considered on "how you never give up on the people you love."

Kitsis calls out to all fans of the show and movie, an often-overlapping audience, with a simple message: "We were so inspired by the film and we were lucky enough that Disney let us bring to life the fanfic we would normally write on the web secretly."

Pretty much every Disney fan's dream job.

Who doesn't like getting to play with their favorites and paid for it? Stories of love, family, personal growth, connection…pretty much every fan's psychological breakdown and study of most characters.
